qubo_embedder 0.2.1

An unofficial library to embed and send optimization (QUBO, Ising) problems to DWave System quantum annealing solvers.

0.2.1

• Removed an unnecessary check in the pseudo-embedding for QUBO problems that returns an empty embedding if all logical qubits have a coefficient of 0.

0.2.0

• Implemented the DWave sampler, DWave API interface and pseudo-embedding algorithms to allow sending QUBO problems to real quantum annealers!
• Samplers now require the Qubo format instead of Hamiltonian objects as input, allowing for a more functional approach. To compensate, QUBO problems can now be created from Hamiltonians:

  final qubo = Qubo.fromHamiltonian(hamiltonian);
  

• New objects:
  • DwaveApi with ApiParams allows a low-level access to the DWave Solver REST API
  • QpuSolverInfo, SolverGraphInfo
  • Embedder
  • Abstract Embedding class with implementations in PseudoEmbedding and MinorEmbedding
  • Encoder, Decoder
  • Constants

0.1.0

• First prerelease containing the essential features and data structures
  • Sampler
  • Qubo
  • Hamiltonian
  • SolutionVector
  • SolutionRecord and SolutionRecordEntry
